(1) the structure size bag filter apparatus (e.g., the amount of flue gas treatment 2,000,000 m? / H or more), accommodate large coal-fired boiler flue gas unit and steel, cement kiln purification. (2) Innovation of low-resistance and high-efficiency bag filter structure to meet the needs of national energy conservation and emission reduction. (3) The pulse technology featuring strong cleaning is upgraded to meet the requirements for cleaning of long filter bags (7~8 meters). (4) Developed airflow distribution technology and computer numerical simulation technology to meet the requirements of reasonable airflow distribution of large baghouses and prolong the service life of filter bags. (5) Development of domestic fibers of PPS, PTFE, polyimide, aramid and polysulfonamide in special filter materials, meeting the requirements of filter materials for complex working conditions of power plants, steel mills, cement plants and waste incineration flue gas purification . (6) Development and application of compound bag filter for deacidification and dust removal to meet the needs of dry deacidification and dust removal processes. (7) Technical upgrade of pulse valve performance and quality, to meet the requirements of bag filter for high-strength cleaning and stable operation. (8) PLC, DCS control technology upgrade and modular products, can meet the control requirements of large and medium and small dust removal systems. Statistics show that in 2016, several key enterprises of bag-type dust collectors have a good production and sales situation. The annual output value of several enterprises has passed the 100 million mark, reaching the best level in history. Exports to foreign countries and even exports to developed countries have seen a large increase in products. However, the price of bag-type dust collectors in China is only 1/3 to 1/10 of that of similar products in developed countries. According to the year-on-year algorithm of the prices of foreign companies, the annual output value of these enterprises should be several hundred million yuan or one billion yuan. The competition in the environmental protection market is becoming more and more fierce, and the dust removal market is no exception. The increasingly attractive prospects in the market and how the dust collector industry is innovating have become a common problem facing the industry. Despite the continuous improvement and breakthroughs in technology, there are still many shortcomings in the baghouse industry in China: (1) The annual output of dust filter media is high, but the overall equipment level is not high, the products are mixed, lack of innovative technology, and the market competition is disorderly. (2) At present, the domestic low-end small-scale workshop-style production lines account for a large proportion, and the production capacity is already surplus. However, there are still enterprises blindly introducing or repeating the construction of low-grade production lines. (3) The functional finishing of the filter material is a weak link. The “raw filter material†without any treatment enters the filter material market with its low cost and low price, and lacks a constraint mechanism. (4) There is a certain degree of blindness and randomness in the selection of filter materials, and there is a lack of in-depth understanding and analysis of the dust removal process and working conditions. (5) Bag type dust filter material manufacturers rarely have a complete set of service system, and have less technical support for the use, maintenance and after-sales of filter materials, which affects the use effect of bag type dust removal. The industry appeals that in order to meet the needs of China's dust removal business and international market competition, the dust removal industry should further increase technology development, strengthen domestic academic exchanges, actively participate in international industry academic activities, grasp new international trends in a timely manner, and continuously promote industry technology. progress.

With the deepening of industrialization and urbanization in China, the pressure on prevention and control of atmospheric pollution continues to increase. "Atmospheric Ten" will increase the inhalable particulate matter (PM10) and fine particulate matter (PM2.5) as characteristic pollutants to an unprecedented height that impairs the health of the people and affects social harmony and stability. At this point, the development of bag dust removal has ushered in an unprecedented spring. In recent years, the level of application technology of bag filter in China has been greatly improved, and it has been widely used in various industries, and the application field is expanding. The development and innovation of bag dust removal technology is embodied in the following aspects:
